On the Numerical Approximation of a Frictional Contact Problem with Normal Compliance
نویسنده
چکیده
In this paper, we consider a frictional contact problem with normal compliance. The problem is formulated as a variational inequality, and is shown to possess a unique solution. The nite element approximation is analyzed, with a Cee alike inequality proved. A major diiculty in actually solving the problem is caused by the presence of a non-diierentiable functional in the formulation of the problem. Here we discuss the regularization method to overcome the diiculty. A-posteriori error estimates are derived.

Analysis and Numerical Approximation of an Elastic Frictional Contact Problem with Normal Compliance
In this paper we consider a problem of frictional contact between an elastic body and an obstacle. The elastic constitutive law is assumed to be nonlinear. The contact is modeled with normal compliance and the associated version of Coulomb's law of dry friction. We present two alternative yet equivalent weak formulations of the problem, and establish existence and uniqueness results for both fo...
متن کاملQuasistatic Frictional Contact and Wear of a Beam
A problem of frictional contact between an elastic beam and a moving foundation and the resulting wear of the beam is considered. The process is assumed to be quasistatic, the contact is modeled with normal compliance, and the wear is described by the Archard law. Existence and uniqueness of the weak solution for the problem is proved using the theory of strongly monotone operators and the Cauc...
متن کاملSystem identification of a beam with frictional contact
The nonlinear system becomes an area with numerous investigations over the past decades. The conventional modal analysis could not be applied on nonlinear continuous system which makes it impossible to construct the reduced order models and obtain system response based on limited number of measurement points. Nonlinear normal modes provide a useful tool for extending modal analysis to nonlinea...
متن کاملDynamic Frictional Contact of a Viscoelastic Beam
Abstract. In this paper, we study the dynamic frictional contact of a viscoelastic beam with a deformable obstacle. The beam is assumed to be situated horizontally and to move, in both horizontal and tangential directions, by the effect of applied forces. The left end of the beam is clamped and the right one is free. Its horizontal displacement is constrained because of the presence of a deform...
متن کاملNumerical Analysis of a Quasistatic Problem of Sliding Frictional Contact with Wear
We consider numerical approximations of a quasistatic problem modeling the sliding frictional contact with wear between a viscoelastic body and a rigid moving foundation. The contact is modeled with the Coulomb's law of dry friction and the wear is described by a version of Archard's law. The variational formulation of the problem consists of a nonlinear evolutionary equation coupled with a tim...
